When grief becomes a diagnosis

After · 9 min read

Prolonged grief disorder is a formal diagnosis, added to the DSM-5-TR and present in the ICD-11, describing grief that remains intense and pervasive well beyond what the person's social, cultural or religious context would expect, and that impairs daily functioning. In DSM-5-TR the death must have occurred a year or more ago for adults, and six months or more for children and adolescents. The core requirement is intense longing for the person, or preoccupation with thoughts of them, together with three or more of eight further symptoms present nearly every day for a month or more. The American Psychiatric Association estimates that 4 to 15 percent of bereaved adults experience it. It is treatable, and the treatments with the strongest evidence are grief specific.

Why it exists

The diagnosis exists because a minority of bereaved people do not follow the ordinary course, and before there was a name for it they were routinely treated for depression instead, with results that were often poor. Naming the condition made it possible to study it, to develop treatments aimed at it specifically, and to have insurers pay for those treatments.

It is worth being honest that the diagnosis is contested. Some clinicians and many bereaved people object to grief being medicalized at all, and to the idea that a duration can mark the boundary of a reasonable response to losing someone. That objection is serious and it is not settled by the existence of criteria.

The strongest argument for the diagnosis is practical rather than philosophical. People with prolonged grief disorder are, by definition, not adapting, and they generally do improve with the right treatment. A category that gets someone to a treatment that works is doing useful work, whatever its conceptual difficulties.

How it actually works

The DSM-5-TR criteria run as follows. The death occurred a year or more ago for an adult, or six months or more for a child or adolescent. The person experiences intense longing or yearning for the person who died, or preoccupation with thoughts or memories of them. Three or more of the following are present nearly every day for a month or more: identity disruption, such as feeling that part of oneself has died; marked disbelief about the death; avoidance of reminders; intense emotional pain such as anger, bitterness or sorrow; difficulty reintegrating into relationships, interests or planning; emotional numbness; a sense that life is meaningless; and intense loneliness. The disturbance must cause clinically significant impairment, and must exceed what the person's social, cultural or religious norms would expect.

The ICD-11 criteria differ, which matters if you are seen by a clinician using them. The World Health Organization's system sets a minimum of six months rather than twelve, requires one of the two separation distress symptoms, and requires one or more of ten accessory symptoms rather than three of eight. A study of a representative German population sample found prevalence of 4.7 percent under DSM-5-TR and 5.4 percent under ICD-11 among bereaved respondents, with substantial but incomplete agreement between the two systems.

The threshold that does most of the work is not time, it is impairment and cultural context. Grief that is intense at eighteen months but does not stop a person living is not the disorder. Grief that has sidelined almost everything else in daily life for a period far longer than expected is what the Columbia Center for Prolonged Grief describes as the actual picture.

Assessment is straightforward and short. A clinician with grief experience can usually establish whether the criteria are met in a single appointment, often using a validated questionnaire. The Columbia Center publishes a self assessment and a therapist directory, which is a reasonable place to start if you are not sure whether to seek an appointment.

Where you stand

You are entitled to a competent assessment rather than an assumption. Prolonged grief disorder is frequently mistaken for depression, and the two are treated differently. If you are offered an antidepressant without any discussion of grief specific treatment, it is reasonable to ask directly whether prolonged grief disorder has been considered.

You are entitled to decline the label and still get help. A diagnosis is a route to treatment and to insurance coverage. It is not an obligation, and the therapies that help prolonged grief also help people who fall short of the criteria.

You are entitled to have your culture taken into account, because the criteria explicitly require it. Both diagnostic systems require that the response exceed the expectations of the person's own social, cultural or religious context. A mourning practice that lasts a year in your tradition is not evidence of disorder, and a clinician unfamiliar with that tradition should be told about it.

Coverage varies. Whether treatment for prolonged grief disorder is covered, and by which plan, depends on your insurer and on your state's mental health parity rules. Ask your plan what it covers for a diagnosed mental health condition, and ask the clinician whether they bill it as such.

What to do

The mistakes that cost people

Concluding you have the disorder because a year has passed and you still hurt a great deal. Duration alone is not the criterion. Impairment and cultural context both have to be met.
Accepting treatment for depression without anyone asking about grief. The two conditions overlap heavily and respond to different treatments.
Waiting for the twelve month mark before asking for any help. Grief specific therapies help people who do not meet the criteria, and nothing is lost by asking early.
Assuming that a diagnosis means the grief was wrong. It describes a course that has become stuck, not a failure of love or of character.

Words you will meet

prolonged grief disorder: A diagnosable condition in which intense grief persists well beyond cultural expectation and impairs daily functioning.
DSM-5-TR: The American Psychiatric Association's diagnostic manual, text revision, which added prolonged grief disorder in 2022.
ICD-11: The World Health Organization's international classification of diseases, which also includes prolonged grief disorder with somewhat different criteria.
separation distress: Intense longing for the person who died, or preoccupation with thoughts of them, which is the core symptom in both systems.
identity disruption: The sense that part of oneself has died along with the person, listed as one of the accessory symptoms.
functional impairment: Measurable interference with work, relationships or daily activities, which is required for the diagnosis in both systems.

What this does not cover

This module does not cover the treatments themselves, which are the subject of the module on what actually works, and it does not cover post traumatic stress disorder or major depressive disorder, both of which can follow a death and both of which are separate diagnoses.
